This is an interesting article from ENT Today looking at outcome measures of snoring and OSA surgery. One can measure hard sleep study data or look at patient-reported outcomes. Either way, surgery for OSA is worth considering for cases where CPAP does not deliver a solution

There is an interesting table comparing the Pros and Cons of patient-reported and physician-recorded data:

POLYSOMNOGRAPHY / SLEEP STUDY (PSG)

+Hard AHI data to compare surgery to baseline

Can show reductions in mortality risks eg if AHI drops from 100 to 50

-Does not capture full clinical picture eg symptom improvement, presence or absence of adverse effects or patient satisfaction with procedure
